Change media-source to use sco-io for HFP codecs.
Replace sco-source with media-source.
sco-source is mostly copypaste from media-source, only differed in the
IO handling.
Change media-sink to use sco-io for HFP codecs.
Move SCO fragmentation to sco-io side.
Replace sco-sink with media-sink.
sco-sink is mostly copypaste from media-sink, and only differed in the
fragmentation detail, which can as well be handled on sco-io side.
Don't try to write data in too large blocks.
This controls the maximum amount of data to send at once. sco-io will
buffer and fragment packets to the right size.
Previously in sco-sink, SO_SNDBUF was not set, so there could be a
longer queue in the socket.
E.g. LDAC doesn't have that. Add the missing guard that was accidentally
dropped in the rewrite.
Also explicitly filter out non-A2DP/BAP codecs that can't be used in
ensure_media_codec
We don't actually have to store the ramp parameters so allocate them on
the stack and then use them to generate the sequence.
Make it possible to generate a sequence into a custom buffer as well.
Make sure we use the right rate (the graph rate) to calculate the number
of samples when converting from time to samples.
Otherwise we won't be able to negotiate with a port that only wants old
style midi.
Instead just negotiate the control link, conversion to old style midi
will be done in the control mixer for the old client.
Fixes#4759
Make a new alsa.use-ucm option that sets api.alsa.use-ucm on the device
it creates (when set).
There is some documentation floating around (thr arch wiki) with this
property.
See #4755
The filter detects unnatural gaps (consisting of 0.0 values) and will
ramp-down or ramp-up the volume when entering/leaving those gaps.
This makes it filter out the pops and clicks you typically get when
pausing and resuming a stream.
See #4745
After AT+CLCC command completion, the calls which has not been listed
should be removed.
This list the calls returned by AT+CLCC to be able to find the ones which
has not been listed but still in the call_list.
Unicast BAP codec switch requires CIG reconfiguration, which cannot be
done if there is an acquired transport.
When doing BAP codec switch, disable nodes of other devices sharing the
same CIG.
To avoid problems with node start/stop, just remove and re-add them.
I'm not aware of any devices that support 48 kHz output in duplex
configuration, so disable that for now.
Doing this properly requires catching errors when on transport Acquire,
and switching to another configuration if the error was due to bad
configuration.
Due to how BAP specification works, it's not necessarily possible to
know whether a configuration was really accepted at earlier stage, and
anyway there's no proper error -> reconfiguration handling currently on
BlueZ side either.
If device supports duplex, show also separate sink-only/source-only
profiles.
Devices don't necessarily support high-quality audio in duplex profile,
so add sink/source only profiles.
This is also a workaround for the current situation that devices may
signal duplex support, but the attempted duplex configuration fails to
work.
Use SelectProperties() DBus API to reconfigure BAP unicast setup.
Add support to spa_bt_ensure_codec() to select whether to configure as
sink/source/duplex.
Simplify codec switching code: determine what switch to perform
immediately in spa_bt_device_ensure_media_codec().
The previous code doing "fallback" switching to various codecs is not
useful, as A2DP generally disconnects on the first failure and all
remote endpoints disappear.
Add iteration over multiple endpoints, for reconfiguring both source and
sink directions at the same time. This is in preparation of supporting
BAP reconfiguration (for A2DP there's usually only one direction
connected at a time).
alsa_write_sync can insert or remove some data from alsa when
resynchronization is needed.
Avail and delay are equal when high precision timestamps are not allowed.
When the high precision timestamps are enabled, the delay is avail
adjusted to current_time.

Use codecs via media_codec in sco-sink instead of implementing the
encoding in-place.
In future, media-sink could replace sco-source to reduce code
duplication.
